YifanZhang commented on KUDU-3006:
----------------------------------
I reproduced this error and printed some logs to debug, some logs were like:
{code:java}
I1122 15:54:18.806080 28648 rebalancer_tool.cc:190] replacing replicas on
healthy ignored tservers
I1122 15:54:18.825372 28648 rebalancer_tool.cc:1438] tablet
6274e4d23add454d97ed7b2d7208a097: not considering replicas for movement since
the tablet's status is 'CONSENSUS_MISMATCH'
{code}
That means a replica is not healthy so the rebalancer tool would not move it,
I'll try to fix it.
